The single-crystal silicon differential pressure transmitter is used to measure the level, density, and flow of liquids, gases, or steam, and then converts it into a 4-20mA DC HART current signal output.

    Features of Single-Crystal Silicon Differential Pressure Transmitter

• 1. The central sensing unit adopts silicon technology with platinum-level accuracy.

• 2. Proprietary dual overload protection diaphragm design, with unidirectional overpressure resistance up to 40MPa.

• 3. The static pressure performance of the single-crystal silicon differential pressure transmitter far surpasses that of capacitive products in the same application, with static pressure error optimally controlled within ±0.05%/10MPa.

• 4. The single-crystal silicon differential pressure transmitter offers an adjustable range ratio of up to 100:1.

• 5. The electromagnetic compatibility (EMC) of the single-crystal silicon differential pressure transmitter complies with GB/T 18268.1-2008.

• 6. High stability, reliability, and extremely low temperature drift. The transmitter's zero point, accuracy, and repeatability remain unchanged for years, requiring no maintenance during long-term operation.

• 7. Three alarm current output modes are available for user selection.

• 8. Linear output and square root output of the differential pressure transmitter can be freely programmed and configured, with a standard 4-20mA/HART bus output.

     The SDPT36 intelligent single-crystal silicon differential pressure transmitter developed by Chenqiong Electronic Technology uses imported single-crystal silicon sensors, combined with a new signal processing system. It offers the advantages of high stability and reliability and can be applied in various fields such as petroleum, chemical, power generation, steel, metallurgy, glass, cement, food, pharmaceuticals, and machinery manufacturing.
